Abstract

1,180,842. Making nuts. GKN SCREWS & FASTENERS Ltd. 27 Dec., 1967 [10 Jan., 1967], No. 1230/67. Heading B3A. [Also in Division F2] A method of manufacturing stiff nuts having four flat portions formed on the outer surface of a collar portion to deform the bore of the collar portions comprises feeding nut blanks on a conveyer 22 to a position between two relatively movable die members 17, and sliding the die members towards each other in a direction 18 to form the flat portions by the engagement of die surface 27. The die surfaces are inclined at an angle of 5-10 degrees to the vertical plane of the nut axis. The flat portions are formed symmetrically and two on each side of a diameter 19 with the angle between adjacent flat portions on opposite sides of the diameter being between 110-130 degrees.
